I have 1 Raq4r and there are quite a few sites hosted on it. I want to get another Raq4r and use something like Rsync to mirror both systems... everything on both systems so if one goes down, the other one will kick in and keep serving up web pages without skipping a beat.

What is the best way to go about doing this? Should I have DNS1 on one server point to all the sites on that server, and in the case DNS1 goes down (and thus also that RAQ) it reverts to DNS2 which would then be the back up raq?

I'm open to all options.

Thanks,

I made a lengthy post about this, and my setup a little while ago.

Basically, you need a ping script on your backup that turns on NAMED with A records for HTTP pointing to your backup if your main server goes down. Just keep MX records pointing to your main server, mail will be queued untill the main server comes back up.
